Devices, systems, and methods are provided for radar elevation angle validation. A radar elevation angle validation device transmit, from a radar, one or more signals towards a corner reflector situated in a direction of the radar. The radar elevation angle validation device may receive, at the radar, reflected signals from the corner reflector. The radar elevation angle validation device may measure signal energy of at least one of the reflected signals. The radar elevation angle validation device may access a baseline dataset based on the measured signal energy. The radar elevation angle validation device may retrieve a radar elevation angle from the baseline dataset corresponding to the measured signal energy. The radar elevation angle validation device may compare the radar elevation angle to a validation threshold. The radar elevation angle validation device may determine a radar validation status based on the comparison.
